It has come to the attention of several moderators that some subverses on the site MAY contain malicious code via submission links.
You are urged to DISABLE THE CSS in your account preferences, click the cog wheel by your user name in the upper right corner.
USE ALL DUE CAUTION BEFORE CLICKING ON ANY LINK POSTS--Consider hovering to view where a link is taking you before you click; if there's any question, do not proceed.
The Admins have been notified.
EDIT TO ADD:
Updated information: The code is a script exploit - maintain caution by hovering over any links before clicking; no reported CSS involvement.
